A San Francisco tech executive whose previous venture was synonymous with Internet piracy has found a way to play nice with Hollywood.

BitTorrent co-founder Ashwin Navin is working with television networks and consumer electronics companies on a new technology called Samba that will deliver enhanced viewing on Internet-connected smart TVs.

Navin said his experiences with BitTorrent, and the backlash engendered by the file-sharing pioneer, spurred his decision to work in collaboration with the entertainment industry instead of pursuing a path of business disruption.

"You can get a lot of great press, you can get all the bloggers and social media folks really excited with statements like, 'I'm here to kill cable,' " said Navin, 35. "But that doesn't actually work. It's not productive, because cable and subscription television is subsidizing and paying for the programming we love."

Navin's San Francisco company, Flingo, draws from the same body of academic research for Samba that underlies the Department of Homeland Security's face-recognition technology to teach smart TVs to "see" the images flickering on the screen.

Comparing content

Like an infant opening her eyes for the first time, the software is trained to recognize actors' faces and objects on the screen. It uses these visual cues to identify a show by comparing it with a database of hundreds of channels of content.

Once Samba determines what a viewer is watching, it delivers contextually relevant content, such as casting information or social media conversations, directly to the TV - as well as to other screens in the room. The software synchronizes the devices automatically, via the Internet, so the viewer doesn't need to download a special application. The supplemental material is available through a Web browser running on a tablet, smartphone or the TV itself.

"From a consumer point of view, (Flingo is ) doing a nice job of stitching these things together based around a TV-centric experience," said Paul Gray, television research director for NPD DisplaySearch. "And not trying to be a PC in your living room - which is the big danger."

Technological glue

Flingo is one of several companies seeking to serve as the technological glue that connects the living room TV with the smartphones, tablets or laptop computers that millions of people have in their hands, along with their TV remote controls. One Nielsen study found that 86 percent of tablet owners and 84 percent of smartphone users said they check these screens while they watch TV. Television networks have been grappling with the intrusion of these small screens, which compete with the TV for viewers' attention.

"If we can find ways to connect those screens, we can deepen the engagement with the show, we can remind people that they are watching TV," said Hardie Tankersley, Fox's vice president of platforms and innovation. "Being able to match the ads that you're seeing on your laptop with the ads that are running on TV - that has tremendous potential for brands, who advertise both on TV and the Web. To be able to synchronize up is really powerful."

Companies such as Zeebox, Yahoo's IntoNow and Shazam Entertainment offer smartphone and tablet applications that identify TV shows and deliver supplementary content to this second, smaller screen - including cast lists, a plot synopsis and interactive features such as polling.

CES announcements

Flingo's Navin is placing his bet on a different screen: the TV. Announcements of partnerships with device makers are expected next week at the Consumer Electronics Show in Las Vegas.

Smart TVs are moving from a novelty to the mainstream, with shipments expected to grow 15 percent worldwide this year, according to NPD DisplaySearch. An estimated 43 million of these devices - TVs that connect to the Internet and provide access to services such as YouTube, Netflix or Hulu - are expected to ship globally this year. That number is projected to reach 95 million by 2016.

This momentum is less obvious in North America, where Internet-connected TVs have been slower to catch on than other parts of the world, Gray said. That's because purchases are linked to media consumption habits.

Navin started Flingo in 2008, creating smart TV applications for networks including A&E, Fox, History Channel, Lifetime, Showtime and TMZ, as well as websites such as Revision3, Funny or Die and College Humor. As a result of this development work, the company has built relationships with more than a dozen major consumer electronics manufacturers, among them LG Electronics, Samsung Electronics, Sony and Vizio. It claims to have published more smart TV apps than any other company in the world - available on more than 15 million devices in 118 countries.

That may position it to take serious advantage of smart TV growth in the United States.

Billionaire entrepreneur Mark Cuban, who saw a demonstration of Flingo at the CES trade show last year and is an investor in the company, says the smart TV "is the last great unmined consumer platform."
